Bill was fourteen years old and in the ninth grade．He had a part time job which got him up at five o'clock．He was a newspaper boy．
Each morning,Bill left the house at five fifteen to go to the center．The newspapers were delivered there by a truck at midnight．He carried them on his bike．
In the winter it was still dark when he got up．But during the rest of the year it was bright．Bill had to deliver the newspapers to his customers（订户）houses in all kinds of weather．He tried to put each paper in the box where it was safe from wind,rain and snow． His customers thought he did a good job．Sometimes they gave him tips （小费）．
Bill made about $70 each month and he was saving some of the money to go to college．He spent the rest on tapes and clothes． Once a month he had to collect money from his customers．Since many o{ them worked during the day,Bill had to get the money al night．Sometimes when Bill was ill,his elder brother had to deliver the newspapers．Once his father had to help him．
Bill has 70 customers now,but he hopes to get more soon．Some day,when he bas many more customers, perhaps Bill will win a prize for being a very good newspaper boy．He wants to win a visit to Europe （欧洲）,but he would be happy enough if he won a new bike．

From the story we know that Bill's part-time job could 
a make him become a college student
b make him stronger
c help him make many good friends 
d help him get what he needed most at that time
为什么选D而不选A?

Bill made about $70 each month and he was saving some of the money to go to college．
送报纸只能帮他赚到上大学的钱,而不能让他变成一个大学生.所以不选 A
再问： 那为什么是D？
再答： D 的意思是可以帮他得到他此时最想要的。

文中提到，他此时最想要的是一辆自行车，或是去欧游玩。 这两个如果这个报童得到奖了，都是可以实现的。而且是通过这个兼职得到的。
